Containers in OpenStack

Overview of this book

Containers are one of the most talked about technologies of recent times. They have become increasingly popular as they are changing the way we develop, deploy, and run software applications. OpenStack gets tremendous traction as it is used by many organizations across the globe and as containers gain in popularity and become complex, it’s necessary for OpenStack to provide various infrastructure resources for containers, such as compute, network, and storage. Containers in OpenStack answers the question, how can OpenStack keep ahead of the increasing challenges of container technology? You will start by getting familiar with container and OpenStack basics, so that you understand how the container ecosystem and OpenStack work together. To understand networking, managing application services and deployment tools, the book has dedicated chapters for different OpenStack projects: Magnum, Zun, Kuryr, Murano, and Kolla. Towards the end, you will be introduced to some best practices to secure your containers and COE on OpenStack, with an overview of using each OpenStack projects for different use cases.

Preface

Murano components


The figure in The Murano dashboard section explains the architecture of Murano. Murano has a similar architecture to other OpenStack components. It also has the API service and an engine as the main components. There are other components as well, such as murano-agent, Murano dashboard, and the python client, that is, murano-pythonclient. Let's take a look at each component in detail.

The Murano API

The Murano API (murano-api) is a WSGI server that serves the API requests of users. The Murano API has different controllers for each resource type. Each controller handles a request for specific resources. They validate the request for permissions, validate the data provided in the request, and create a DB object for the resource with the input data. The request is forwarded to the murano-engine service. Upon receiving a response from murano-engine, the murano-api service returns the response to the user.
